Neuron

tree-like structures that branch out from the soma

Synapse

Receptor

Dendrites

Neuron

junction between axon of sending neuron and dendrite of receiving neuron

Soma

Axon

5 True/False questions

Soma → Cell Body

True False

Interneurons: → carry outgoing information from brain and spinal cord to the muscles and the glands

True False

Threshold → individual nerve cells that communicate directly or indirectly with other neurons

True False

Myelin Sheath → insulated tubes around the axon that speed up transmission of neural impulse

True False

The Neural Impulse → 1. Threshold: the level of stimulation required to trigger a neural impulse in the receiving neuron.
2. Impulse travels from the soma down the axon to terminal button
3. At the terminal, vesicles move to the membrane, attach and release chemicals into the synapse
